Joint Message from Chairs and Director
The Environmental Partnership continues to demonstrate meaningful progress in methane emissions reductions across the U.S. oil and natural gas industry. Built on its core principles of taking action, learning, and collaborating, TEP provides a unique platform for operators of all sizes to share knowledge, evaluate emerging technologies, and implement practical solutions that improve environmental performance.
Operations are complex and vary based on each company’s unique operational footprint, but progress is accelerated when companies share lessons learned, test new technologies, and advance best practices together. The accomplishments of TEP participants in 2025 reflect our members’ deep and ongoing commitment to responsible energy development.
Through TEP’s Leak Detection and Repair Performance Program, participating companies expanded their use of advanced detection technologies, conducted inspections more frequently, and reduced repair times when emissions were identified. Collectively, companies inspected more than 195,000 sites, with 65% of these sites surveyed voluntarily.
TEP’s Flare Management Program also highlighted strong operational performance, achieving a 9.5% reduction in flare intensity and a 27% reduction in total flare volumes reported from the previous year. TEP members have reduced their reported flaring intensity by over 78% since the program started in 2019.
These accomplishments build on years of industry investment, innovation, and collaboration. Methane reduction is not a one-size-fits-all challenge. Operators must tailor solutions to their specific assets, operating environments, and emissions profiles. Through TEP, companies gain access to shared experiences and best practices that help them identify the most effective approaches for their operations while accelerating learning across the industry. Since 2024, the Partnership has awarded over 815 continuing education credit hours to TEP workshop participants.
TEP members remain united in their commitment to responsibly develop America’s energy resources while continuing to advance environmental performance. Their collective ingenuity, dedication, and willingness to collaborate position the partnership to continue to make meaningful progress and emissions reductions in the years to come.

Accelerating
Progress Year Over Year
Since TEP’s start, we have seen measurable progress year-over-year through the actions participating companies have taken to reduce emissions.

Flare Management Progress
TEP and its members are committed to reducing flaring by advancing best practices, promoting the beneficial use of associated gas, and improving flare reliability and efficiency when flaring is necessary.
In 2025, participating companies continued to reduce their flaring, achieving a 9.4% reduction in flare intensity and a 27% reduction in total flare volumes compared to the previous year, even as U.S. oil and gas production grew by 3% and 4%, respectively, during the same period.
- 9.4% reduction in flare intensity
- 27% reduction in total flare volumes
Emissions Detection and Monitoring Practices
TEP participants implement robust leak detection and repair (LDAR) programs within their organizations to find and fix unintentional emissions from equipment as soon as possible.
In 2025, 65% of the reported sites monitored were conducted voluntarily, and aerial-based monitoring technologies were used on over 32% of those sites surveyed.
- 65% sites monitored were conducted voluntarily
- 32% used aerial-based monitoring technologies

Sharing
Knowledge Across Membership and Partners
Many of the unique challenges that individual operators face are more manageable when tackled together through open dialogue with industry peers and other experts.
A cornerstone of the Partnership is to provide opportunities for operators to convene, learn, and share valuable information about new strategies and emerging technologies to reduce emissions.
Regional and Topic-Focused Workshops
In 2025, TEP held four in-person workshops — bringing together air quality experts to promote sharing of operational learnings and solutions to reduce methane emissions and further our industry’s progress toward improving environmental performance.
Our two topic-focused workshops targeted practices to reduce emissions from flare operations and compressor and engine driver equipment. Regional workshops in the Appalachia and Permian Basin regions discussed a range of issues — including basin-wide measurement collaborations, storage tank control system solutions, emissions quantification approaches, strategies for managing third-party emissions event notifications, covered tank and flare facility design strategies, implementing a closed loop gas capture system to minimize flaring, and strategies to incorporate satellite detections into mitigation practices.
- 300+ members attended these workshops in 2025.
- TEP awarded 815+ continuing education credits since 2024.
Compressor and Engine Driver Guidance Development
TEP has developed a foundational learning document and shorter tailored guidance for operations and monitoring personnel on natural gas-fired reciprocating compressors and engine driver emissions reduction strategies, consolidating company operating best practices focused on maintenance and monitoring strategies.
METEC Sponsorship and Workshop
The collaboration between TEP and Colorado State University’s Methane Emissions Technology Evaluation (METEC) has been foundational to the partnership since its start.
METEC has yielded a variety of studies and learnings to improve operational practices to continue driving down emissions.
In January 2025, The Environmental Partnership and METEC held a two-day workshop at the METEC research facilities in Fort Collins to learn about recent and planned methane monitoring experiments and gain input from operators on revised testing protocols to better evaluate monitoring technologies.
Pneumatics Emissions Projects
Through analysis of Kathairos nitrogen consumption data across TEP member companies, TEP is studying emission reduction practices for pneumatic controllers and working to generate robust, empirical methane emissions factors for pneumatic devices. Empirical methane emission factors could support regulatory and voluntary reporting frameworks, reduce redundant measurement costs, and improve emissions accuracy for pneumatic devices.
Annual Meeting, Conference and Tech Forum
In December, more than 170 operators, key industry stakeholders, and partners gathered in Houston for our 8th annual meeting and conference. Attendees learned about advancements in methane detection technologies, how third parties and state regulatory agencies are using these technologies, and how operators can rapidly and effectively respond to methane emission detections.
Operator panelists shared perspectives on opportunities for leveraging AI capabilities within methane mitigation strategies and discussed how to drive cultural adoption of proactive methane mitigation management within organizations. TEP closed out the conference with an investor panel where experts from JP Morgan, BlackRock and CalSTRS shared their perspectives on methane performance and how it is increasingly viewed as a signal of operational excellence.
The TEP Technology Forum was held in conjunction with the conference and included exhibits from over twenty industry partners.
